2.Application of differential air shaft
A.The applicable Machine
It is used for slitting machine,coating machine,cutting machine,printing machine,compounding machine,paper making machine,bag making machine, embossing machine and so on .It can greatly improve the working efficiency and the quality of products.

B.The applicable Material
Differential air shaft has been widely used in plastic film including electronic, capacitor, battery film, plastic wrap,packaging,
composite film, metal foil such as copper foil and aluminum foil, paper and pvc sheet.

3.The advantages of our products
1). High quality material for the base shaft and spare parts

The body of the differential shaft is made from steel or stainless steel.We will check the surface roughness,straightness, dynamic
balance,cylindrical and so on to make sure it's qualified to use.

The friction plate can be made from polyurethane, polyethylene,or rubber.They has good consistency of dynamic and static friction
coefficient, less affected by temperature ,high wear resistance and long service life.It's good to realize max tension
required.And we can customize according to customer’s drawing or special requirement.

2).Surface Treatment
Blacking,polishing,anodize,chrome plating,zinc plating,nickel plating,tinting.

The overall quenching and tempering treatment improve the wear resistance and corrosion resistance,which make it possible to use in a variety of environment.

3). Quality control
We have the quality control system during the whole production from the very beginning to the end and our principle is to make
sure each shaft is qualified.

Feature of Air Differential Rewinding Core Shafts
* Difference in material thickness often arises when unwinding plastic films or other material. In the process of constant winding, this difference can lead to obvious discrepancy in outside diameter of roll, and slight discrepancy in winding torque under this situation.
* After some winding rotation, some rolls may become very tight, and meanwhile, some other rolls may start to loosen, leasing to quality decline in product eventually.

* Our differential air shaft with slipping friction can ensure the highest winding quality, and by keeping proper tension on all rolls throughout the winding operation, materials will not show any problem.

* It works under the theory that friction rings slip constantly in center of air shaft, and to keep same tension, some rings slip faster than others. So tension of each roll can be controlled accurately, and permanent tension can also be gained to guarantee the quality of roll.

* According to different roll diameters, to control air pressure of air bag and to guarantee tension, a constant air pressure source kept by rotary joint is required
